I bought a Lenevo IdeaPad Y500.
I erase its windows and install Ubuntu 12.04.2 LTS on it.
I can not use my webcam on my laptop. I check Skype and guvcview non of them can detect my webcam.
The following link said it will be working by upgrading to Ubuntu 13.04.
Lenovo Y500 camera not working.

I did the update but no change. this is the error that I get from guvcview. no codec detected for H264 no codec detected for MP3 - (lavc) Checking video mode 640x480@32bpp : OK libv4l2: error turning on stream: Input/output error VIDIOC_STREAMON - Unable to start capture: Input/output error libv4l2: error turning on stream: Input/output error VIDIOC_STREAMON - Unable to start capture: Input/output error Also there is no change in skype.
